A refinement of Gorenstein flat dimension via the flat–cotorsion theory

LW Christensen, S Estrada, L Liang, P Thompson… - Journal of Algebra, 2021 - Elsevier
We introduce a refinement of the Gorenstein flat dimension for complexes over an
associative ring—the Gorenstein flat-cotorsion dimension—and prove that it, unlike the …

Locally type and -coherent categories

D Bravo, J Gillespie, MA Pérez - arXiv preprint arXiv:1908.10987, 2019 - arxiv.org
We study finiteness conditions in Grothendieck categories by introducing the concepts of
objects of type $\text {FP} _n $ and studying their closure properties with respect to short …

The stable category of Gorenstein flat sheaves on a Noetherian scheme

L Christensen, S Estrada, P Thompson - Proceedings of the American …, 2021 - ams.org
For a semiseparated noetherian scheme, we show that the category of cotorsion Gorenstein
flat quasi-coherent sheaves is Frobenius and a natural non-affine analogue of the category …

[HTML][HTML] Strongly Gorenstein projective, injective, and flat modules

D Bennis, N Mahdou - Journal of Pure and Applied Algebra, 2007 - Elsevier
In this paper, we study a particular case of Gorenstein projective, injective, and flat modules,
which we call, respectively, strongly Gorenstein projective, injective, and flat modules. These …

Homotopy categories of unbounded complexes of projective modules

Y Yoshino - Journal of the London Mathematical Society, 2022 - Wiley Online Library
We develop in this paper the stable theory for projective complexes, by which we mean to
consider a chain complex of finitely generated projective modules as an object of the factor …

Strongly Gorenstein flat modules and dimensions

N Mahdou, M Tamekkante - Chinese Annals of Mathematics, Series B, 2011 - Springer
There is a variety of nice results about strongly Gorenstein flat modules over coherent rings.
These results are done by Ding, Lie and Mao. The aim of this paper is to generalize some of …

Cohen–Macaulay modules,(co) torsion pairs and virtually Gorenstein algebras

A Beligiannis - Journal of Algebra, 2005 - Elsevier
We use torsion pairs in stable categories and cotorsion pairs in modules categories to study,
in general infinitely generated, Cohen–Macaulay modules and (a generalization of) …

Gorenstein injective envelopes and covers over two sided noetherian rings

A Iacob - Communications in Algebra, 2017 - Taylor & Francis
We prove that the class of Gorenstein injective modules is both enveloping and covering
over a two sided noetherian ring such that the character modules of Gorenstein injective …

Model structures on categories of complexes over Ding-Chen rings

G Yang, Z Liu, L Liang - Communications in Algebra, 2013 - Taylor & Francis
The so-called Ding–Chen ring is an n-FC ring which is both left and right coherent, and has
both left and right self FP-injecitve dimensions at most n for some non-negative integer n. In …
